As the core components, transfer the DC power to AC power, we use the high frequency transformer, ensure the stable and full AC output, no failure. Adapted the imported capacitor, large electricity, better performance, longer lifetime, safer usage. True copper inductance, filter the wave form, ensure the true pure sine wave AC output, your equipment. No electromagnetic interference to your equipment, such as no noise for TV, FM radio, . With the big radiating flange, better cooling performance, ensure the best inverter working condition.
